## Discrepancy

WHILE PERFORMING ENGINE FIRE EXTINGUISHER SYSTEM TEST IAW B1900C MM CAMP NR2 INSPECTION TEMP REVISION 26-1, FOUND NR 1 AND NR 2 ENGINE SQUIB POWER SWITCH DISCONNECTED FROM ANNUNCIATOR/ ACTUATOR ASSEMBLY.  THIS A RECURRENT PROBLEM WITH THIS STYLE SWITCH ASSEMBLY. FAILURE OF THE SQUIB SWITCH ATTACHMENT DISABLES THE FIRE EXTINGUISHER SYSTEM AND COULD CAUSE LOSS OF LIFE IN THE EVENT OF A FIRE.  THERE IS NO WAY FOR THE FLIGHT CREW TO GROUND TEST THIS SYSTEM FOR THIS TYPE OF FAILURE.
